On his mother's bedside, an enigmatic guy approached him and offered to give his mother a new life at the expense of his own life expectancy.

In order to save his terminally-ill mother, Dong Cuican signs a "contract" with a mysterious man for trading his own time for his dying mother's life. After recovery, his mother Yan Jinyu returns to the age of 20 and is still healthy. By virtue of her maturity and optimism, she lives a more exciting life that she never expected. However, not to worry his mother, Dong Cuican conceals the truth about his life, and takes on the cost of the contract alone.
